Wall-mounted air conditioning in Finchley
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. A single wall-mounted unit is often all a bedroom or sunny living room in Finchley needs.
In a semi or terrace in Finchley, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. Finchley lies roughly 8 miles from central London, and we cover it as part of London. Postcode districts we cover here include N3.
Prices in Finchley
In London, our guide range for wall-mounted air conditioning is £1,495–£3,895 per room, including VAT. Prices here sit above the national middle, reflecting London labour rates and parking and access costs. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) would typically be £2,045–£2,845 here.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
We book surveys in Finchley at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Finchley usually takes one to two hours.
